7 Claims. (Cl. 57-1) This invention relates to a device for marking the filled bobbins of a spinning frame as the frame 1s being manually doifed to eliminate the necessity of the doffer walking completely around the spinning frame for marking each of the iilled bobbins, prior to executing the dofiing operation.

lt is a conventional practice in textile mills where splnning frames are manually doifed for each doffer to doff bobbins of a particular grade of yarn. As 1t 1s difhcult t visually determine the different grades of yarn, each doler before commencing the dofling operation walks completely around the spinning frame marking the thread of each bobbin with chalk of a particular color to designate the particular grade of the yarn of the bobbins which he doffs, so that proper separation of the bobbins of different grades can be thereafter readily accomplished.

It is an object of the present invention to provide a bobbin marker which is constructed and arranged to be readily mounted detachably upon a doing box used by a dolfer for receiving the lled bobbins and for holding the empty bobbins which are applied to the spinning frame to replace the filled bobbins by the doffer 1n the doing operation, so that as the doifer pushes the doiiing box in front of him along the spinning frame the marker, which is supported by the dolfing box, will mark each filled bobbin with a proper colored mark before the filled bobbin is reached by the doffer.

More particularly, it is an aim of the present invention to provide a bobbin marker of extremely simple construction which may be detachably mounted readily upon a doing box and which includes relatively adjustable parts for positioning the marker to facilitate the marking of each bobbin and which additionally allows a yielding of the marking element away from the bobbin as it moves across a circumferential portion thereof.

Various other objects and advantages of the invention will hereafter become more fully apparent from the following description of the drawing, illustrating a presently preferred embodiment thereof, and wherein: v

Figure l is a side elevational View of the bobbin marker shown in an applied position and in the process of marking the yarn of a filled bobbing Figure 2 is a top plan view thereof; l

Figure 3 is an enlarged fragmentary vertical sectiona view taken substantially along a plane as indicated by the line 3--3 of Figure 2, and

Figure 4 is an enlarged longitudinal sectional View taken substantially along a plane as indicated by the line 4-4 of Figure 1.

Referring more specifically to the drawing, the bobbin marker in its entirety and comprising the invention is designated generally 5 and includes a substantially U- shaped clamp 6 having an arcuate intermediate or bight portion 7 and depending legs 3 and 9. The leg 9 is preferably provided with a pair of laterally spaced threaded openings 10 through which setscrews 11 are threaded inwardly. The intermediate or bight portion 7 is pro- States Patent 0 rice vided with a slot 12 which extends longitudinally of the clamp 6, as seen in Figure 3.

A screw 13 extends outwardly through the slot 12 and is disposed with the head of the screw engaging the inner side of the bight portion 7 and with the shank of the screw extending outwardly from said bight portion into the restricted end of a volute-type coil spring 14, the smallest end convolution of which bears against said outer side of the bight portion 7. A nut 15 is disposed between said smallest spring convolution 16 and the next adjacent convolution, said nut being larger than the opening of the convolution 16. The screw 13 is threaded through the nut 15 and is tightened for clamping the convolution 16 against the bight portion 7 in a desired adjusted position of the spring 14 relatively to the clamp 6. The uppermost, largest convolution of the spring 14 terminates in an arm 17 forming an extension of said uppermost spring convolution and which projects substantially tangentially from the spring 14 outwardly over the side 8 of the clamp 6. The spring arm 17 terminates at its outer end in a transversely extending downwardly bowed portion 18 which engages around the outer side of the bottom part of a relatively wide ring member 2i) and which is secured thereto in any suitable manner as by welding, as indicated at 21. An extension of the opposite end of the transverse portion 18 constitutes a terminal leg 19 which extends back from the transverse portion 18 toward the spring 14 and which constitutes one end of the strand from which said spring is formed.

A setscrew 22 is threaded radially inward through the other upper part of the ring member 20. Said setscrew 22 and the setscrews 11 are preferably provided with wing type screw heads 23 by means of which said setscrews may be manually turned with the thumb and index finger. An elongated barrel or sleeve 24 has a portion disposed loosely in the ring member 20 and is clamped therein by tightening the setscrew 22. The barrel or sleeve 24 is preferably secured in the ring member 20 as illustrated in the drawing so that the barrel extends only a short distance outwardly of said ring member and inwardly a substantial distance. However, as the description proceeds it will be obvious that the positioning of the barrel 24 in the ring member 20 may be varied considerably to meet the requirements for use of the bobbin marker 5. 'The barrel Vor sleeve 24 is split from end-to-end thereof as seen at 25 to provide a relatively wide slot so that said barrel can be restricted in diameter by tightening of the adjusting screw 22.

A piece of chalk or a crayon 26 extends through the barrel 24 and outwardly of the forward end of said barrel which is located remote to the spring 14. Accordingly, by tightening the setscrew 22 the barrel 24 is not only adjustably secured in the ringmember 20 but the chalk or crayon 26 is adjustably clamped in the barrel 24 by the restriction thereof to position the tapered or scribing end 27 of the element 26 a desired distance outwardly from the ring member 20.

An eye 28 is suitably secured to the outer side of the barrel 24, near the inner end thereof and circumferentially spaced from the slot 25. The eye 28 projects laterally from the barrel 24 and is disposed so that the return arm 19 extends through the eye 28, as seen in Figure 4, to steady the barrel 24 relatively to the spring 14 and to prevent rotation of the barrel in the ring member 20.

To illustrate the application and use of the bobbn marker 5, a portion of one side of a spinning frame 3h is illustrated in Figures l and 2 including a few of the filled bobbins 31. Likewise, a portion of a conventional dofling box 32 is illustrated in Figures l, 2 and 3. The dofing box 32 is mounted on wheels or rollers and has a rear end section 33 for containing empty bobbins to replace the filled bobbins removed from the spinning frame 30, and a larger forward space or compartment 34 in which the filled bobbins are deposited. The dong box 32 has a side wall 35; constituting an inner side Wall thereof and which is adapted to move alongthe longitudinal side edges of the spinning frame 30 as the doing box 32 is pushed in advance of the doler. A portion of one of said longitudinal side edges of the spinning frame 30 is illustrated in Figures 1 and 2 and designated 36.

The clamp 6 is disposed over the upper edge of the box wall 35 near the rear end of its front compartment 34 and with the clamp leg 8 on the outer side of the wall 35 and the clamp leg 9 on the inner side thereof. The setscrews 11 are `then manually tightened for securing the clamp 6 to the wall 35 for mounting the bobbin marker on the doiiing box 32, as illustrated in Figures 1 to 3. When thus disposed, the spring 14 supports the barrel 24 so that the chalk or crayon 26 whichv is clamped in said barrel is disposed with its pointed or scribing end 27 positioned to mark the yarn 37 of each lled bobbin 31, mounted on the spinning frame 30, as the marker 5 passes the illed bobbins 31 located adjacent the spinning frame edge 36, along which the doing box 32 is being moved. The screw 13.can be adjustably clamped relatively to the slot 12 to vary the disposition of the spring 14 relatively to the clamp 6, and the barrel 24'may be adjustably mounted in the ring and the chalk or crayon 26 adjustably mounted in the barrel 24, so that as the marker 5 moves past its position of Figure 2 the parts thereof supported by the clamp 6 will be spring biased from right to left so as to position the scribing end 27 to engage the yarn 37 of the next lled bobbin 31 and to apply a mark thereto as the marker 5 moves past the bobbin and the chalk orrayon yields from left to right. Thus, the scribing end 27 will make a mark on the yarn 37 of each bobbin circumferentially through a substantial arc not exceeding 180. It will be obvious that the chalk or crayon 26 may be of any desired color. It will also be apparent that the barrel 24 and ring 20 may be of different internal diameters to accommodate chalk or crayon of different diameters.

It will thus be seen that a colored mark is applied to the yarn.37 of each filled bobbin before it is removed from the spinning frame 30 and deposited in the dotling box compartment 34 thus eliminating the separate operation previously required and wherein the doier before commencing to dof a spinning frame walked completely along both sides thereof marking the yarn of each of the bobbins with a colored stripe by means of a piece ofr chalk or crayon held in the hand. It will also be apparent that the `barrel '24 will etect a material savings in the chalk or crayon as only a slight portion thereof must necessarily extend from the outer end of the barrel so that very short pieces may be used thereby minimizing waste.

Various modications and changes are contemplated and may obviously be resorted to, without departing from the spirit or scope of the invention as hereinafter dened by the appended claims. i
